Interesting. So the commercialization of water cooling took some of the interest out of it?

Maybe it just put things into perspective, in terms of cost (my take); It's never been cost efficient, and wasn't ever anywhere near it i.e. a decent water cooling solution is still ~$200, versus any air cooled solution, most under $50.

I think also that we've exhausted water block designs, and that we're past any new innovation.
